A key concern was rainfall run-off into waterways in areas recently affected by fires, which have the potential to contain debris, soil, ash, trees and rocks, the State Emergency Service advised.

Since midday yesterday, the SES have been called out to more than 140 calls across the state, with 85 from the central region, 26 from the state’s northeast and 13 from the northwest, a SES spokeswoman said.

She said Frankston, with 40 call-outs, was the worst hit in metropolitan Melbourne.

“The main call outs have been to trees down and some minor roof damage,” she said.
